How to mount Absolute Black Oval Chainring

Using Hollowtech II BB Removal Tool (like BBB BTL-116 or Shimano TL-FC41 ), carefully open the lockring that holds the chainring on the crank(normal threads). Once the lockring is removed, take off old chainring, re-grease the splines on the crank. Place new oval chainring with convex side to the crank. Chainring/crank has special splines that only fit one way. Close the lockring to 35-50Nm of force. Chainring is only compatible with XTR CN-M9100 chains. Using other chains may cause chain to drop very easily from the chainring due to thinner than usual teeth

Chain compatibility

These specific chainrings are only compatible with Shimano HG+ 12 speed chains (CN-M9100, CN-M8100 , CN-M7100) due to specific tooth profile. Using other chains may cause chain to drop very easily from the chainring due to thinner than usual teeth.

souplesse de pédalage dans les cotés sinon on ne fait la différence pour un amateur cela semble être un atout en terme de vélocité. Moi j'y crois et je l'ai ressenti mais cela ne fait pas de fous une bête de course ;-)
